Hi all,
Please help me to run the simplest example with CXF. After spending ten hours
I still can pass any arguments to my methods.
This is my service:
@WebService(name="CalculatorService", serviceName="CalculatorService")
public class CalculatorService {
@WebMethod
public double addNumbers(double v1, double v2) {
return v1 + v2;
}
}
Upon it I generate using cxf plugin the following wsdl
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="CalculatorService"
targetNamespace="http://cfx.foo.com/";
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/";

xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/";>
<wsdl:types>

</xs:sequence>
</xs:complexType>

type="tns:CalculatorService">
<soap:binding style="document"

<wsdl:operation name="addNumbers">

<wsdl:input name="addNumbers">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="addNumbersResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="CalculatorService">
<wsdl:port name="CalculatorServicePort"
binding="tns:CalculatorServiceSoapBinding">
<soap:address location="http://localhost:9090/CalculatorServicePort"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
Upon wsdl I generate java code. When I call my generated services I see the
following

I can’t understand why my arguments are ignored. Is there some dependency
problems? Then why there is no any exceptions? Please, help me to solve this
problem.
